Fortum's Sustainability Report 2013 is published online in Finnish and English and can be read at annualreport2013.fortum.com. The report is based on the GRI G3.1 Guidelines. The Finnish version of the Sustainability Report is given limited assurance by Deloitte & Touche Oy, Fortum Corporation's financial auditors. The assurance scope covers the Finnish version of the sustainability reporting material presented at annualreport2013.fortum.com .
In addition to the G3.1 Guidelines Fortum has also reported, when applicable, some of the indicators presented in the Electric Utility Sector Supplement of the GRI. Sector-specific additions to the G3.1 indicators have not been acknowledged. Fortum has conducted a self-assessment on the comprehensiveness of the reporting, as required by the GRI. The application level has also been reviewed by the assurance provider, and both parties are in agreement that Fortum has followed application level B+ of the GRI 3.1 Guidelines. In its
reporting, Fortum has also adhered to the AA1000 Accountability Principles Standard (AA1000 APS).
The report content is not updated after assurance, and any amendments to the content will be reported the following year. Deloitte & Touche Oy has also provided limited assurance for emission calculations (Scope 1-3) based on the GHG Protocol according to the requirements published by CDP (Verification of Climate Data). The assurance report will be delivered to CDP as part of Fortum's CDP reporting.
